Dollar tree VS Poundland LED lamp and hack.
Вставка
- Опубліковано 21 жов 2024
- After seeing Adrian Black explore a dollar store lamp on his channel it made me realise that I've not taken a look at the most recent Poundland lamps.
That has now been rectified and the results were very interesting. The highest power version of the lamp is similar to the one Adrian took apart, but optimised for our higher voltage.
These are the first 36V 12 chip LEDs I've seen. If you look at the lower power modified lamp at the end of the video you may see that one LED was visibly dimmer. I probed it with a meter and found that it was an 18V six chip LED to fine tune the voltage.
These lamps use a power supply that acts like an electronic resistor, so it's most efficient to get the combined LED voltage as close to the mains voltage as possible with a small margin for regulation.
Here's Adrian's video:-
• Dollar Tree $1 LED Bul...
Very interesting and completely hackable lamp with the intriguing feature of pre-heating its own PCB for easier component modifications. With a higher value sense resistor the current will be lower and the heat of the LEDs will be reduced to the point that the lamp could potentially last for a very long time.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of UA-cam's advertising algorithms allowing it to be a bit more dangerous and naughty.
"Does he give the children presents then touch them inappropriately?"
I have been watching this channel far too long to be caught off guard by that one
I would have been disappointed if he didn't make some kind of comment like that. ;)
Enticing the kitties into the popemobile with candy.
That segue was absolute perfection.
That's exactly why I like Clive
That's actually quite accurate. Also, add racism/blackface and kidnapping kids.
You can tell when Clive gets excited by how quickly he tears into something! High excitement indeed this time!

The funny hat is a bishop's miter. Probably intended to be St. Nicholas, who was in fact a bishop.
I did laugh at "papal helmet." 🤣
I've recently bought more than a hundred of these current-regulating lamps, ripped out the aluminium disc boards, and made a powerful lighting for my room by sticking those to a aluminium profile, and soldering some wires to connect them all in parallel. Turned out to be a surprisingly cost-effective solution, I am periodically searching for anything better and this approach still wins by a substantial margin.
It was very fun to walk out the store with two plastic bags full of LED lamps =)
It’s amazing how much they can pack
Into so little! Great video I love seeing the implementations they are coming up with to drive LEDs 👍
My house is lit with mostly Dollar Tree lamps, and so far they have proven to be reliable & pleasant. Their "equivalent" 40W & 60W give off a nice warm light, while the 100W examples are best for work areas or cellars - bright but an ugly bluish.
I bought a bunch of Dollar Tree lamps for the new house. They're disappointing. Most died within 18 months. Some as soon as 6 months. Not worth it.
2 concepts, one concept uses a transformer to drop voltage, then a little bridge rectifier chip and a capacitor to smooth it out, these are connected to generally a couple of the 1w type chips.
The other concept is like in this video, instead of dropping voltage, they decide to accept a huge voltage, and to just have surface mount style LED's that have multiple LED's inside each chip, essentially the large enough series ends up adding up to the high voltage, and obviously it isn't AC, it's DC via a bridge rectifier, some chips and a capacitor at the back.
In my experience the longest lasting and most effective is the first form. I have had around 4-5 LED's fail via an LED diode burnout, and all of those have been the second high voltage type that have burned out.
Thus I now prefer to stick to the drop down voltage ones that use transformers and then use just a couple of higher power LED diodes (such as a few 1w ones).
Clive, i don't know why but i just never get sick of this stuff. Perhaps because i took everything apart as a child, much to the chagrin of my mother.
But i did learn a hell of a lot that way, including what a good whack from the mains feels like - instant respect and a bit of fear. Great stuff.
I like the way you present, and also hack the circuit in realtime
Clive am falling in love with your videos. Yesterday I found the same led lamp as you showed. You answered all my Doubts. Thank you so much!! Keep the good content up!
Clive, the hat is also used for Bishops in the Catholic Religion. that image I think is supposed to be St Nicholas of Myra? he was a Bishop of the ancient Greek maritime city of Myra in Asia Minor during the time of the Roman Empire back in the early 4th century. born March 15th, 270 AD Died Dec 6th, 343 AD.
This type of hat is called a mitre. The shape give its name to the mitral valve in the heart.
Yes, it is the Dutch "Sinterklaas", also known as the Bishop of Myra.
He used to have a servant, "Black Pete" ( Zwarte Piet), but protest groups in the Netherlands ( Kick out Zwarte Piet) managed to kill this tradition recently. It seemed a very "racist" thing to them.
Santa Claus = St Nicholas, who was a Bishop, later dubbed by The Beach Boys 'Little Saint Nick'.
Duco Maritiem zwarte piet is still around, he just isn’t depicted (in the mainstream celebration) by guys in literal blackface any more.
I like how Saint Nicholas (allegedly) punched a guy in the face because he said that God the Father and Jesus were only made of a similar substance, not the same substance. This is called the Arian heresy.
9:35 "iceberg lamps" that's brilliant 😂. These are more like the lamps I get from walmart. Great Value brand. I haven't had a Phillip's apart yet. I have the dimmable setup in living room. If the lamp has ben run on high for a while then if I dim it down it will actually cut off, for a minute. Then light back up, after a few minutes, that's the heat regulation right, that's what I've always thought. Cheers from Kansas.
9:28 "I could sell that on eBay as art" - but you'd increase its value by several orders of magnitude if you taped a banana to it
did someone call TJ?
"Does he leave gifts for children and then touch them inappropriately?" Well damn. Now the rest of the day is basically a wash because I know that nothing will top that.
Jay Cee , yes, exactly, although my first laugh was when he said:“Uuhh, it‘s tight in here, hmmm“.
Well, you have to figure something is up (or the Mrs. is a frigid bitch) since Santa Claus comes only once a year, and it's on the night that he spends out of the house.
He sees you when you're sleeping. He knows when you're awake.
I don't know a damn thing about electricity but I love your videos lol
@Mai Mariarti Better get some metal Chopsticks, they work way better for sticking into outlets because they actually fit in there.
If you want, you can lick the chopsticks after sticking them in if you are still alive.
Just in case someone doesn't get it: Its a Joke don't do it!

Jyv Ben he actually died on December 6th, so the Belgian celebration kind of makes more sense. The Dutch are just impatient I guess 😆
@@mlenstra In fact, the 5th was the night children put their shoe in front of the fireplace. 'Sint Nicolaas' then put a present in the shoe for the little one to find it on the morning of the 6th. As traditions change over time, placing the shoe 'schoentje zetten' became custom a few times in the two or three weeks before the 6th, and the night of the 5th went 'pakjesavond'
@@fiskurtjorn we have something like this in romania with candys in boots on the night before 6th of december in romania too
Question for you Clive:
Seeing as all lamps but the Dubai lamps are engineered to fail quickly, what would be the feasibility of designing a lamp-holder extension to modify the incoming power, for the mass market, in order to keep these bulbs running cooler and give them a slightly lower output but a longer life? Extensions already exist for switching, recepticle addition (U.S. crazy deathwish stuff), bluetooth switching, etc. It seems that it could be done in a smallish package. Thoughts?
Also, if you could get a chinese manufacturer on board- there would be a market in "Big Clive Forever Lamps" and most, myself included, would pay a premium for them. I keep looking for some to modify with which I can replace the cover but no luck yet.
Have you seen my dooby lamp video? It shows a hack to reduce power externally on many lamps.

A nice shiny L-E-D!…
Clive got a question, do you actually trust Dollar lights like these in your house? In the US we can get decent brand name LEDs for around $1.30-$1.50 a bulb. Which would be close to a British pound so theoretically your Pound Lights might be the same quality.
But our Dollar Store light are equivalent of about 0.75 British pound and I have a hard time trusting their quality. Even the brand lights I've had quite a few failures with flickering or just going out all together.
I worry much cheaper and something may be likely to catch fire...
Poundland is good in complying with British electrical standards. But nothing is quite as fire proof as the old glass and metal lamps.
@@bigclivedotcom, thanks for the reply. This is true but unfortunately they are power hogs also.
I actually did have a regular 60w bulb at one point short somehow and melted the glass. No clue how it happened, wish I kept the bulb.
Was many years ago though.
Making those lower wattage would be perfect for one of those bathroom vanities that 3-5 lights at the top.
Next to the general thumbs up for Clive and his need for ripping stuff apart, this time a double thumbs up for the product placement of cuberdons! Geldhof makes the best ones 😀. Tip: try to get them as fresh as possible (as in: get them locally near the factory 😉)
Clive can only begin to understand how much pleasure it gave me to see a professional be as haphazard with his soldering as I am. I always thought I was shamefully bad. 😂
You’re assuming he’s a professional. 🤓🧙🏼♂️
For some reason every time I click one of your videos I expect to have some profound realization.
I usually just get to watch you break some junk, instead.
Great teardown
Great design, love to drive LED via currently drive
Thanks for sharing👍😀
That's Clive. Always good that you exist!
Come for the circuits. Stay for the candy reviews
I've found that chucking up the bulb in a small lathe makes disassembling the LED bulbs a lot easier and cleaner looking. I only disassemble them to see if there are any parts that can be salvaged after the bulb quits working. For the most part though, they don't tend to have any because most of the stuff is surface mounted and I don't have the patience to try to solder surface mounted parts.
Adrian Black's channel is great 👍👍
Nice diy mod.
If I find similar bulbs here in Denmark I think I would want to make them about half the wattage. I find it disconcerning that led bulbs only lasts one to two years on average for us.
Thank you for sharing. Keep it up.
I use a good few GU10 LED lamps of various makes. My experience is that ventilation (cooling of the lamp enclosure) is the life limiting factor. Small metal bell shaped hoods facing downwards are very prone to overheating the GU10, and where there is good airflow the lamps seem to last much longer. The LED Cobs will last 1,000 hours, true, but the power conversion components are the weak spot. If the rubber sucker tool is mislaid the GU10 can be a curse to remove.
one of the proudest moments early on in my learning about this stuff was finding a black spot on an led in one of these bulbs that had failed, winding thin wire around the led to short it out and bringing the bulb to life! saving one pound in exchange for massive fire risk didn't seem worth it in the end. but anyway, it pleased me.
This is the exact light I wanted to send you!
been a subscriber to Adrian Black's channel for quite some time already
They really are getting a bit better then?? I do like Adrian he get almost as excited as yourself over these things bless him :)
Interesting "self-preheating" of the aluminium plate to solder in new resistor! "Thar's hot-hot-hothot!!"
"I could sell them on eBay. As Iceberg-lamp"
Since eBay sellers tend to watch bigclive, I guess it won't be long
Easy way to remove the "screw housing" is to screw it into a lamp socket until it starts to tighten, then loosen it a bit and just pull so that the housing gets stuck in the socket and you can easily unscrew it.
You could solder a couple of wires to the sense resistor connections, and insert a variable resistor drilled out the side (with a limit resistor) for a dimmer circuit ;)
I'm still a little confused as to how it's achieving a voltage higher than the input voltage without an inductor.
Is it using the peak to peak difference in the AC to boost the final voltage?
The peak voltage of the sinewave is approximately 1.4 times the RMS voltage.
bigclivedotcom that’s kind of what I thought. Thanks for clarifying! :D
I'm pleased by the plug-in electrolytics: since that's a part that generally fails after a while (even after reducing the power and therefore heat), making it simple to replace makes it a great candidate for a "forever bulb".
To me it looked more like an ice-cream cone than an iceberg. Brilliant hack. Good luck on monday, Clive.
I wander if i can send him a part see whats wrong with it pir sensor for flood light
If used outdoors, probably water damage.
bigclivedotcom its never used
You don't have to heat the board to solder on it. I use these boards to drive the LED strips used in florescent replacement LED tubes. I solder on them with my cheapo 60w Amazon iron.
I've seen self regulating ones where the light board only has the LEDs and resistors and the regulating circuitry is on a breakout board shoved into a slot under the board and down into the socket
At 5:40 I would say that they could use different LED brands/providers and make them compete while using the same circuit and maximizing their profit! Great video thank you Clive!
"Dollar store" confusingly, just means "discount store". "Dollar tree" means everything is a dollar. Confusing as hell for foreigners, but there you go.
vs - PoundLand! :) I actually had to process that name for a few cycles!
@@doncooper3946 What did you think it was? A 1980's term for sex? "Ima take her to pound land tonight."
@@xenonram Imagine for a moment that you've never heard the word pound being used for anything aside from a unit of weight and therefore aren't familiar with the name PoundLand.
Yeah, it's easy enough to figure out what it is after a few seconds but it's not as if everyone in the world just automatically knows what PoundLand is...
> Dollar tree" means everything is a dollar. Confusing as hell for foreigners
Tell me about it! I went looking for them in a forest.
Don't forget "Dollar General" to add to the confusion
How do I send you bulbs mate there is a place near me that sells 16w maxim bulbs just like these there are pretty big as well and I opened one and it had 3 capacitors a coil all sorts I don't know what there is but would love to send you one to look at thanks.
My solution to mod the 100w version was a bit more crude. The 100w version has two of these chips in them, So I ripped one out. As they run in parallel that effectively halved the brightness. I really wanted to swap the resistors, but my soldering iron is too weak.
Another hack to these types of lamps could be to replace the sense resistor with a potentiometer and basically use the built-in chip as a dimmer
The 'Santa' figure is Saint Nicholas (to Anglicise his name) wearing his Bishop's Mitre. He is one of the 'original' Christian winter figures associated with Christmas before Thomas Nash re-designed him as the more secular & family friendly Santa Claus we are familiar with. 🤓
It’s Thomas Nast for those who want to look him up.
Pope Santa...leaves gifts for children before inappropriately touching them
Big Clive owes me a new keyboard because sprayed coffee is not covered under warranty :)
Following along at home, this is kinda fun! Though mine was using 4-chip LEDs, and a BP5131H. I intend on swapping out the ~5000K LEDs for 2700Ks and putting it back together. Maybe with a remote control circuit shoved in there, we’ll see. But since I can’t find any 12V 2700K chips, I’ll need to check that it won’t overheat and change the current set resistor(s) if necessary.
Completely unrelated question here, if these new German submarines use new electric cells to power the boats keep mechanical noises at a minimum during their operation doesn’t that high voltage used create a frequency? If an opposing navy wanted to detect them could a device be made to detect those extremely high electric frequencies?
I wonder if this new circuit design will last longer? I've had a few of the 'Electek' branded ones, which have only lasted about 6 months, with daily use in a table lamp.
A while back, when I was in 'Home bargains' (in the UK) I was looking at their 'e-luminate' branded LED lamps & spotted some 9 watt 'Daylight' 6500K versions, which I thought I would try in the porch light, once the existing CFL lamp expires, I'm still waiting - that GE stick CFL has been in nightly use for the last 15 years & still going strong! Must have done well in excess of 50,000 hours!
Hey big C, do the bulbs use the same circuit if they use 110v rather than 220v? Thanks
That 2 watts bulb will work for life. With that artistic plastic dome, i think it's worthing smething :)
Well done on replacing the resistor! My hands are to shaky to do that.
The only sucky thing about those lamps is that if one LED fails, they stop working. I have repaired a couple of them by removing the burnt one and bridging the contacts.
What is the type of the LEDs? I would sleep safer by properly replacing the burnt ones.
Another interesting video Clive, thanks.
Every Dollar Tree bulb disassembly seems to find a different circuit. I bought a number of $1 bulbs from the same box. Some had switching power supplies and others had the current limiting chip. All the bulbs were used in open fixtures. All of the switching supply bulbs failed with burned out LEDs. Some of the current limit circuits also failed. Overall, about one-third of the Dollar Tree bulbs have failed within a year under almost ideal operating conditions. Hopefully the changing design means that the failure rate has decreased. I will need to buy a new batch to replace the failed bulbs and monitor those to see if there has been an improvement in the bulb life.
The 27 ohm resistor may be used as inexpensive fuse specially when is covered by heat shrink .
i have a 9 watt led plate. i completely removed the current sence resistor and it became a dark night lamp that provides just enough light to find my way around in the dark and not disturb my sleep. my style of tweaking components here is by placing it over a candle at reasonable height and then using a tweezer to remove things. then when soldering tiny things, i may mask the surroundings with some paper tape to not overflow solder in the surrounding areas. they also place these things over an iron and perform surgery.
Love your videos doing this sort of investigation.
I once did a bit of exploring inside a Status 9w globe and discovered the electrolytic cap was mounted on the same side as the leds and had a plastic base that circuit was a capacitor dropper I believe.
I would like to know how much RF interference these different lights give. The smog produced by different lamps means that radio equipment does not work well.
It's always funny to see everyone wanting to change LED lamps into low power versions that barely give out enough light to see anything, while I always said that a lamp couldn't be bright enough. Well, now I've found a lamp that is not just bright enough for my liking, but even a bit too much: it's an Osram E27 lamp that draws 21.5W and supposedly is as bright as a 150W incandescent. Together with another E27 LED from Philips that draws 18.5W and supposedly is as bright as a 130-140W incandescent lamp, I used both to light up my room and my desk (both pointing towards the ceiling and indirectly lighting it). Those were now replaced with 2 other Osram LEDs that draw 14W each and are supposed to be as bright as a 100W incandescent, and that's now what is bright enough, but not too bright either.
Hey clive pls will u reply my one question. Plsss,
I made ir remote controlled using standalone Atmega 328 pu microcontroller which controls 8 relays but 1 relay connected to AC fan which after switching on it makes all relays turn off it's like it get reset to off positions. What should I do to avoid this🙄
Your soldering gives me anxiety lol love the channel
Here's a thought, if you wired in a variable resistor to that programming resistor point, would it make the bulb dimmable, even if it'd be at the bulb rather than the lightswitch? :D
At 18:00 your line voltage had dropped by three volts as the load current had dropped by two milliamps. Coincidence? I think not!
Replacing U1 with a pot (and series resistor) gives a dimmable lamp with no flicker at all. The knob would get rather warm though I suppose.
And yes, I noticed the upper left LED was dimmer at the end of the video. Thanks for explaining that.
Clive, how much do you pay for these bulbs? Dollar shops in Oz don’t carry anything like these in my area.
16:05 It's "Sint Nikolaas" or "Saint Nicholas" in English, it's basically the original version of Santa. The celebration is on the eve of his nameday (december 6th), mainly celebrated on a big scale in The Netherlands and Belgium. It came into excistence in the Middle Ages.
@@TintelFruit That's the eve, his name day is december 6th
@@TintelFruit "eve of his nameday" IS the night before, the "eve before his nameday" is pleonasm at best.. plain wrong at worst. Like how "christmas eve" is the evening BEFORE christmas.
thank you for making the educational print-out/prop, I finally get these things now. So the easiest way to drive these LED lights with DC, is to make your own and buy similar LED chips in a bag from Alibaba/Aliexpress?
Dang, wish I'd seen this video before the one I watched yesterday and lamented on how difficult it was to disassemble. I'd have known what to expect. BUT, mine had a glass globe :) and there was some sort of silicone-like substance all within the lower shell and under the screw base. If I find another, I'll try dismantling it a little less destructively. Otherwise, mine is like the first? one that has transformer, etc. on vertical board that plugs into the LED panel.
Now to go look up Adrian's video... :)
Hello Clive, the "santa pope" is actually called Sinterklaas; who brings presents to all the good little children in Belgium and the Netherlands on december 6th.
His helper (zwarte piet / black peter) has become something of a controversial figure these past few years. You see, he's black from going throught the chimney, but it seems chimneys give people great big afros and obscenely red lips as well.
If only Dick van Dyke had known, Mary poppins would have been a completely different movie.
Another hack for you if you take off the dome/light diffuser you can grow plants with them try to get as many Led as possible. is it possible you could show us how to convert them to the right at 12 V DC
Great vid as always Clive. Also loving the rave caused by video fuckery on your voltmeter
The biscuit has a miter on but they got the crozier wrong. Santa in some cases was a bishop but a bishop’s crozier should open outwards, a crozier that has its hook opening inwards designates an abbot.
there is definitely an AMSR element to Clive's audio delivery ... and he also know's his stuff...
Basicly every dutfch person shouting at their screen: "that is not santa!'
I'm curious about how much heat the bulb actually gives off. My mother in law always uses a low-wattage incandescent to incubate chicken eggs, but those are getting harder to find. I wonder how many LED bulbs she'd have to run to heat up the chamber the same amount.
You can get little radiant heaters that screw into a lamp holder.
@@bigclivedotcom Ah, yeah. Totally forgot about those reptile "bulbs". Cheers!
Interesting. "Cuberdons can only be preserved for about three weeks, after which period the inside begins to crystallize. This limited preservability is the reason why cuberdons are infrequently exported outside Belgium."
Is using a capacitive dropper more of a european thing due to using 240V? I've gone through a good number of various led lamps and I have never seen one being used, being in Canada and on 110v .
They are better suited to higher voltages and lower wattage lamps.
Don't forget Electronupdate as well.
I want to put 4' LED tubes in my RV. (The 120 volt ballast bypass type) Do you have an idea on how to rewire them for 12 volts?
They will be optimised for higher voltage. You'd be better using 12V strip-lights or putting sections of 12V LED tape in existing lights.
I have learned so much from your content,thankyou
I love this hacking around impromptu work. I've been doing the same thing myself, with limited success.
Just bought a 9w 6500k hoping to convert it down to 12 volt. But all lamps are 36 volt, what a bummer.
I need it to attract insects at night using a 12 volt battery.
Is it it possible to convert it?
I've got some Maxim 16w 1,500 lumen bulbs, just tested a couple and they both seemed to waver between 16.9w and 18w. Don't know if that's my cheap watt meter though.
we've come a long way from filament. are there more advancements in lamps/bulbs to come? or are LEDs as good as it's gonna get?
This is about as simple as it could get. It's possible that they might evolve into a flip chip panel like the 50/100W style "driverless" LEDs did, but that might end up costing more due to the larger area of phosphor loaded gel. So maybe the discrete LEDs will be with us for a while.
I guess continually teleporting tiny amounts of Star plasma into a vacuum tube is quite a ways off....
I'm working on a way to separate my light being from my body to light my room. Just need a few more tibetan bowls.
B&Q are currently flogging off a bunch of lighting items, including a 20W circular ceiling fixture for six quid (was thirty allegedly). It has a separate PSU and a built in dimmer feature. Power on.. full brightness. Off and back on quickly.. half brightness... off and back on again quickly.. low brightness. I bought a couple to make in to portable spot lights. If you are near a B&Q you might want to take a look.
Lol, pink "sissy squad" calculator. You do have a sense of good humor.
Great hack. I've got to give it a try.
I suppose these current regulated lamps are good if you're going to just whack them into a socket and use them at their rated power. Those of us who want to run them at lower power find them a bit troublesome, as I've mentioned in comments to another video.
26:30 Wouldn't the hot air gun on your Yihua soldering station have made this a helluva lot easier?
The lamps with simple linear current regulation are perfect for use with a series resistor or capacitor. The onboard current regulator will just never need to regulate the current itself.
I am guessing the 'papal Santa' is St. Nicholas.
Papal Santa? It's literally a «saint» from Vatican, I think.
If we wanna replace a burned led with a resistor to revive the lamp, what value and wattage should we use? Can you show the math?
Dissasembled with you very similar 8.5W from Osram [ LED Value Classic ]. Oddly enough it has no visible flicker (tried camera test too) The chip used is BP5116, voltage across the cap is about 600V, killer, with those rods sticking so high reminds me of shocker. I call that bulb pingpong, it bounces back when you throw it.
I’m just wondering.
Would it be possible to solder another resistor in parallel to achieve the desired resistance?
Lowering the total resistance would increase the LED current.
bigclivedotcom
Firstly thanks for replying, I feel honoured.
My maths isn’t so good, but what I meant is 2 resistors to achieve 100 ohms...no idea if that possible
@@andyischillin6724 Adding another resistor in parallel will always lower the total value. It would have been nice to just add another in the vacant space.

Thanks again...that’s that query resolved Love your channel 👍🏻
2.45 volts. a piece. For 12 per cob. And on the 120 grid bulb, I have a bunch running on 4.7 ohm resisters. They have a problem with a short life span.
